Question

Point P divides a line segment AB in k: 1 A is at (2,4) and B is at(10, -12) Also, p is lies on x axis​

Answer 1

Step-by-step explanation:

Let P divide AB in k:1

⇒1=

k+1

4k+2

⇒4k+2=k+1

⇒3k=−1⇒k=−1/3

⇒ P divides AB externally in 1:3 ⇒

PB

PA

=

3

1

⇒3PA=PB

⇒3PA=PA+AB

⇒2PA=AB⇒PA/AB=1/2
